Install Windows 7/Vista from USB Drive

This guide works 100% for Vista & Windows 7. The main advantage is that by using USB drive you will be able to install Windows7/Vista in just 15 minutes. You can also use this bootable USB drive on netbook which doesn't have a DVD optical drive. The method is very simple and you can use without any hassles. Needless to say that your motherboard should support USB boot feature to make use of the bootable USB drive.

  • USB Flash Drive (Minimum 4 GB).
  • Windows 7/Vista installation files. 
1. Plug-in your USB Flash drive to USB port and move all the contents from USB drive to a safe location on your system.

2. Open command prompt with admin rights. Use any of the below methods to open command prompt with admin right.
* Type cmd in start menu search box and hit Ctrl+Shift+Enter.
* Go to start menu > All programs > Accessories, right click on command prompt and select run as administrator.

3. You need to know about the USB drive a little bit. Type in the following commands in the command prompt:
First type DISKPART and hit enter.
Next type LIST DISK command and note down the disk number (ex: disk 1)

4. Next type all the below commands one by one. Here I assume that your disk drive no is "DISK 1". If you have DISK 2 as your USB Flash drive then use DISK 2. Refer the above step to confirm it. So below are the commands you need to type and execute one by one:







Dont close the command prompt as we need to execute one more command at the next step. Just minimize it.

5. Next insert your Windows7/Vista DVD into the optical drive and check the drive letter of the DVD drive. In this guide I will assume that your DVD drive letter is "E" and USB drive letter is "F". (open my computer to know about it).

6. Maximize the minimize command prompt in the in the 4th step. Type the following command now:

E: CD BOOT and hit enter. (Where "E" is your DVD drive letter.)

CD BOOT and hit enter. 

BOOTSECT.EXE /NT60 F: (where "F" is your USB drive letter. ) and hit enter.

7. Copy your Windows7/Vista DVD contents to the USB flash drive. 

8. your USB drive is ready to boot and install windows7/Vista. Only thing you need to change the boot priority at the BIOS to USB from the HDD or CD ROM drive.

Note: If you are not able to boot after following this guide means you haven't set the BIOS priority to USB. If you got any problem in following this guide feel free to ask questions by leaving comment.
